An important aspect in the quality of the three-dimensional perception produced by any stereoscopic production is the precision of its left/right image registration. Tests show that pixel-precise stereoscopic image registration and convergence improves viewer’s three-dimensional perception by reducing viewing discomfort.1 Current software tools generally rely on techniques like 50/50 (onionskin) for camera system and left/right post-production image alignment. Recent stereoscopic software toolset beta tests indicate that these alignment techniques make pixel-accurate registration difficult to achieve. A review of 70 stereo pairs sampled from seven stereoscopic feature films, released from 2009 to 2012, revealed that the majority lacked a precise point of convergence. Extended viewing of inaccurate stereoscopic convergence leads to viewer fatigue and discomfort. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
